I saw something interesting a few years ago on a clear star filled night.
There was a light traveling two to three times faster than how an airplane at a high altitude would look at night.
The object flew in a straight path for 7-8 seconds when it suddenly made a 90 degree turn, while simultaneously turning into two lights going in opposite directions.
The two lights had the same brightness and speed of the original light, and made no noise or flash when while flying or dividing.
I watch the two lights travel away from each other for around 12-15 seconds until they were out of my view.
No alcohol or drugs were involved in this sighting.
